- Underground roots biomass 地下根系生物量
- We found that roots biomass increased but the ratio of root to shoot decrease with successional stage extend. 一般来说,根系的垂直分布是较浅的,尤其是细根。
- Root biomass of winter wheat in 0~30 cm and 0~100 cm soil layers was studied using root core and dig sampling method. 用挖坑冲洗法和改良根钻法研究了耕层(0~30cm)和1m土体内冬小麦根系生物量及其空间分布。
- S ratio (belowground to aboveground biomass ratio) has been widely used for estimating root biomass. 利用根冠比(R:S)和地上生物量来估算地下生物量是目前常用的方法,但目前缺乏根冠比的数据。

- The variety of Baici with low N efficiency had a decreased root biomass compared to other genotypes under N stress condition in the two light intensity. 在不同光照水平低氮胁迫时,氮低效品种白瓷与其它三个品种相比,根系的形态指标均有不同程度的降低。
- Shoot and root biomass of white maize and black maize significantly decreased in Cd and pyrene contaminated soil than that in uncontaminated soil, especially for root biomass. 这种毒害效应多环芳烃和重金属的复合作用比其单独作用要强烈很多[12]。
- any of various fleshy edible underground roots or tubers. 各种可食用的肉质地下根或块茎。
- Further more, the research of root biomass and its distribution in succession can provide the new theoretic bases for forest dynamics, also maybe the one focus of the belowground ecology. 在演替过程中,根系生物量及其分布动态的研究,可以为森林群落动态学提供新的理论基础,是未来地下生态学研究的焦点之一。
- The root biomass, stem biomass and total biomass of seedling in gap center plots were ratherish higher than those of seedling in gap middle plots, but the difference was not evident. 经过一个生长季后,林窗中心样地中幼苗的根生物量、茎生物量和总生物量均略高于林窗中部样地的幼苗,但差异并不显著。
